Yep. The 3429 symbol rate is BROKEN in virtually all RCI288 data pumps.

If you negotiate it you're fscked. This is a serious BITCH to fix, by the
way, since its rather difficult to know if you've got a screwed modem on the
other end. About the only way I can figure to RELIABLY know is to figure
out a way to detect the "very slow transfer rate" in the DSP and renegotiate
down if you see it happening.
